}Expand description
Data needed to construct a script thread.
NB: DO NOT add any Senders or Receivers here! pcwalton will have to rewrite your code if you do! Use IPC senders and receivers instead.
Fields§

top_level_browsing_context_id: TopLevelBrowsingContextIdThe ID of the top-level browsing context this script is part of.
opener: Option<BrowsingContextId>The ID of the opener, if any.
inherited_secure_context: Option<bool>Loading into a Secure Context
control_chan: IpcSender<ConstellationControlMsg>A channel with which messages can be sent to us (the script thread).
control_port: IpcReceiver<ConstellationControlMsg>A port on which messages sent by the constellation to script can be received.
script_to_constellation_chan: ScriptToConstellationChanA channel on which messages can be sent to the constellation from script.
background_hang_monitor_register: Box<dyn BackgroundHangMonitorRegister>A handle to register script-(and associated layout-)threads for hang monitoring.

window_size: WindowSizeDataInformation about the initial window size.
pipeline_namespace_id: PipelineNamespaceIdThe ID of the pipeline namespace for this script thread.
content_process_shutdown_chan: Sender<()>A ping will be sent on this channel once the script thread shuts down.
webgl_chan: Option<WebGLPipeline>A channel to the WebGL thread used in this pipeline.
webxr_registry: RegistryThe XR device registry
webrender_document: DocumentIdThe Webrender document ID associated with this thread.
webrender_api_sender: WebrenderIpcSenderFIXME(victor): The Webrender API sender in this constellation’s pipeline
